CORKSCREW-MACHINE.

SPECIFICATION forming part of Letters Patent No. 777,161, dated December13, 1904. Application filed April 12,1904. Serial No. 202,780. (Nomodel.)

To all whom it may concern:

Be it known that I, ALFRED A.V1eNos, a citizen of the United States,residing at Canton, in the county of Stark and State of Ohio, haveinvented certain new and useful Improvements in Oorkscrew-lVIachines;and I do hereby declare that the following is a full, clear, and exactdescription of the same, reference being bad to the annexed drawings,making a part of this specification, and to the numerals of referencemarked thereon. in which Figure 1 is a top view showing the differentparts properly arranged and illustrating a corkscrew partially formed.Fig. 2 is an end view showing a section of the corkscrew-blank. Fig. 3is a section on line 3 3, Fig. 1, looking toward the left. Fig. 4c is aview showing a completed corkscrew. Figs. 5 and 6 are detached views ofthe corkscrew-blank, showing the blank end bent in dotted lines. Fig. 7is a sectional view of the screw-threaded shaft and the different partslocated thereon, showing the side view of the corkscrew-forming mandreland the operating-shaft, except at the point where the corkscrew-formingmandrel and shaft are joined together, which parts are shown in section.Fig. 8 is aview showing a portion of the machine located upon a benchand illustrating the position of the blank clamp-lever designed to beoperated by the foot. Fig. 9 is a detached view of the corkscrew-forming die, and illustrating a modified form from that shown inFigs. 1 and 7.

The present invention has relation to machines designed and calculatedfor forming corkscrews from blanks, and the corkscrews designed to beformed are especially adapted to be attached to knife-handles. However,I do not desire to be confined to this particular and exclusive use.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawings.

In the accompanying drawings, 1 and 2 represent the end housings andmembers, which are held in proper relative position by means of suitabletie-bars 3. The housings or side members 1 and 2 are provided with theflanges 4:, which flanges are preferably formed integral with thehousings or side members 1 and 2 and are for the purpose of providingsuitable bearings for the power-shaft 5, which power-shaft is providedwith the crank 6. Upon the shaft 5 is securely mounted the pin ion 7,which pinion is for the purpose hereinafter described.

To the end member 1 is securely attached the screw threaded shaft 8,which screwthreaded shaft is held against rotation by means of theset-screw 9. The screw-threaded shaftS is formed hollow and has locatedtherein the mandrel-operating shaft 10,which mandrel-operatingshaft isprovided with the crank 11. To the mandrel-opcrating shaft 10 isattached the corkscrew-forming mandrel 12 by means of the coupling-pin13. In the drawings I have illustrated the corkscrew-forming mandrelprovided with a shank 14, which shank is seated in the socket 15, saidsocket being formed in the end of the mandrel-operating shaft 10; but Ido not desire to be confined to this particular manner of attaching thecorlc screw-forming mandrel, as the only object is to provide some meansfor so connecting the mandrel that it will rotate with the shaft 10 atthe time said shaft is rotated.

To the side member or housing 2 is attached the clamp-block 16, whichclamp-block may be held by the set-screw 17.

To the housing 2 is pivotally attached the lever 18, which lever isprovided with a clampblock 19, which clamp-block is so located that itwill clamp the corkscrew-blank 20 when the free end of the lever 18 ispressed downward, thereby securely holding the corkscrew-blank duringthe time the convolutions of the corkscrew are formed.

The screw-threaded shaft 8 is provided with screw convolutions of thesame pitch as the convolutions of the mandrel 12, by which arrangementthe gear-ring 21, together with the flange-nut 22, will movelongitudinally when rotary motion is imparted to the gear-ring21 bymeans of the pinion 7, said pinion 7 being formed of such a width thatthe gear-ring will not be moved out of mesh by thelongitudinal movementof the gear-ring 21.

To the flange-nut 22 is securely attached the corkscrew-forming arm ordie 23, which arm or die rotates around the mandrel 12 at the timerotary motion is imparted to the ge'arring 21.

In use the blank 20 is placed in the position l illustrated in Fig. 1,said blank being first bent as illustrated in dotted lines, Figs. 5 and6, and the bend placed in the first convolution of the mandrel 12, afterwhich rotary motion is imparted to the ring 21, together with thedifferent parts attached thereto, and as the arm or die 23 rotatesaround the mandrel it will bend the blank into the form shown in Fig. 1.It will be understood that the arm or die moves away from the extremeend of the mandrel as it rotates around said mandrel, the screw-threadsupon the screw-threaded shaft 8 causing the gear-ring 21 to move bymeans of the nut 22, which nut is located upon the screw-threaded shaft8, as illustrated in Fig. 7. After the cork-screw has been properlyformed the pin 2 is withdrawn from the position illustrated in Fig. 7,which discon nects the shaft 10 from the screw-threaded shaft 8 andpermits the shaft 10 to be rotated, which rotation imparts a rotarymovement to the mandrel 12, and owing to the fact that the blank beingheld in fixed position the convolutions 0f the mandrel 12 draw saidmandrel backward or away from the clamping devices, which leaves theformed corkscrew in such a position that it can be easily removed fromits clamp. After the finished corkscrew has been removed the shaft 10 ismoved endwise until it is brought into the position illustrated in Fig.7 and the pin 24 again placed in the position shown in said Fig. 7.

It will be understood that the pin 24. holds the shaft 10, together withthe corkscrewforming mandrel, against rotation during the time thecorkscrew is being formed.

The lever 18 is located in position to be operated by hand; but ifdesired to operate by the foot the lever 25 is provided and located asshown in Fig. 8 and the connecting-rod 26 connected thereto, the bottomend of said rod being attached to the lever 27, by which arrangement thefoot-lever can be used to clamp the blank.

In Fig. 9 the arm 28 is provided with the bar 29, which bar is providedwith a grooved wheel or roller 30, which grooved roller will come incontact with the blank 20 and bend the blank in the same manner that thedie-arm 23 bends said blank. The object of attaching the bar 29 as shownis to allow said arm to come and go to and from the mandrel 12. Thespring 31 is for the purpose of crowding the bar 29 toward the mandrel12, by which arrangement the corkscrew proper is pointed at its extremeend.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a machine for forming corkscrews, a suitable frame, a power-shafthaving mounted thereon and rotating therewith a pinion, a gear-ringmeshing with the pinion, said gearring mounted upon a nut, ascrew-threaded shaft held in fixed position, an operating-shaft havingdetachably connected thereto a mandrel provided with convolutions, theconvolutions corresponding in pitch with the convolutions of the fixedshaft, adie arm or bar secured to the nut-mounted upon the screwthreadedshaft, substantially as and for the purpose specified.

2. In a corkscrew-forming machine the combination of a suitable frame apower-shaft journaled thereto, said power-shaft provided with a pinion,a gear meshing with the pinion, said gear mounted concentrically upon ascrew-threaded shaft and the screw-threaded shaft held in fixedposition, an operating-shaft located within the screw threaded shaft, acorkscrew-forming mandrel detachably connected to the operating-shaft,and means for holding the operating-shaft against rotation, and acorkscrew-forming die rotatable with the gear meshing with the pinionupon the power-shaft, substantially as and for the purpose specified.

3. In a machine for forming corkscrews, a frame, a power-shaft journaledin the frame, a screw-threaded shaft held in fixed position, anoperating-shaft located Within the screwthreaded shaft movablelongitudinally therein, a corkscrew-forming mandrel rotatable with theoperating-shaft, a gear mounted upon the screw-threaded shaft andmovable longitudinally thereon said gear meshing withAa pinion mountedupon the power-shaft, aforming-die rotatable around thecorkscrew-forming mandrel, and means for clamping the corkscrew blank,substantially as and for the purpose specified.

A. In a corkscrew-forming machine,a frame, a power shaft journaledtherein, a screwthreaded shaft held in fixed position, a gear mountedupon the screw-threaded shaft, said gear adapted to move longitudinallyupon the shaft by its rotation, a corkscrew-forming mandrel providedwith grooved convolutions corresponding in pitch with the convolutionsof the screw-threads upon the fixed shaft, and a forming-die, anoperating-shaft and a pin adapted to hold the shaft against rotation,and a lever adapted to clamp the corkscrew-blank, substantially as andfor the purpose specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
